Effects of Replacing Commercial Fish Meal With Invasive Suckermouth Catfish on Growth, Health, and Economic Performance of Climbing Perch Anabas testudineus
The introduction of invasive suckermouth catfish (SMC) Hypostomus plecostomus has greatly affected the freshwater ecosystems in Bangladesh, posing a significant threat to indigenous fish species. This species is not commonly harvested and consumed, sparking debate over whether to eradicate it from the natural waterbody or repurpose it beneficially. This study explored the feasibility of utilizing SMC as a partial or complete replacement of commercial fish meal (CFM) in the diets of climbing perch Anabas testudineus, assessing impacts on growth performance, whole-body composition, hematobiochemical parameters, intestinal and liver health, and economic viability. Five isoproteic (32% crude protein) and isocaloric (9% crude lipid) diets were formulated with varying SMC levels: (0% [D1, control], 25% [D2], 50% [D3], 75% [D4], and 100% [D5]) and fed to fish until satiety over 90 days. Diets D1–D3 significantly improved palatability, growth metrics (final weight, weight gain, and specific growth rate), and feed utilization (feed conversion ratio and protein efficiency; p < 0.05), compared to D4 and D5. Enhanced levels of white blood cells, lymphocytes, and platelets were also recorded in D1–D3 (p < 0.05). Blood biochemical parameters varied significantly across treatments (p < 0.05), but no specific trend was observed. Superior intestinal integrity characterized by abundant goblet cells, intact stratum compactum, and well-developed villi was observed in D1–D3, along with improved liver morphology, particularly in D3. Economically, D1–D3 treatments yielded better outcomes, including higher production, reduced feed cost, increased revenue, gross margin, return on investment (ROI), and profit index (PI). Overall, replacing CFM with SMC up to 50% proved effective, supporting optimal growth, health, and profitability in A. testudineus, while offering a sustainable strategy to mitigate the ecological impact of this invasive species.
期刊介绍:
International in perspective, Aquaculture Research is published 12 times a year and specifically addresses research and reference needs of all working and studying within the many varied areas of aquaculture. The Journal regularly publishes papers on applied or scientific research relevant to freshwater, brackish, and marine aquaculture. It covers all aquatic organisms, floristic and faunistic, related directly or indirectly to human consumption. The journal also includes review articles, short communications and technical papers. Young scientists are particularly encouraged to submit short communications based on their own research.
